Question

little help plz? Determine which of the following is the correct equilibrium expression for the chemical reaction: Answer choices are below.

Answer 1

Kc = [CaO] [O2] / [CaCO3]

Step-by-step explanation:

Equilibrium constant, Kc is simply defined as the ratio of the concentration of products raised to their coefficient to the concentration of the reactants raised to their coefficient.

Thus, we can write the equation for the equilibrium constant, Kc for the reaction given in the question above as follow:

CaCO3(s) <==> CaO(s) + O2(g)

Kc = [CaO] [O2] / [CaCO3]
